We offer a variety of chemistry group tests (e.g. small and large
animal panels) for both mammalian and non-mammalian species. Some
of our chemistry tests are not incorporated as panels and have to
be requested individually. We prefer serum (red top tube) for chemistry
testing (all our reference intervals are based on serum), with the
exception of stat samples and samples submitted after 3 00 pm. The
latter samples should be submitted in heparin (green top tube). Please
refer to Sample Submission for more information on the required samples
for chemistry tests. There are some differences in reference intervals
for some analytes in serum versus heparinized plasma. Please refer
to our Reference Intervals for more information.
We use an automated wet chemistry analyzer, the Hitachi 917, for our
chemistry tests. As well as performing chemistry tests themselves,
the Hitachi provides useful information about interferences in the
sample. This is shown on our chemistry reports as special chemistry
tests, the lipemic, hemolytic, and icteric indices.
Some of our tests are also performed using other instrumentation.
For example, patients on bromide therapy have artefactually high chloride
(because bromide and chloride are both measured in the assay) with
the Hitachi, but our bench instrument, the chloridometer, is less
affected by this artefact. For this reason, it is always good practice
to inform the laboratory of any medication the patient may be on so
that we can modify our methods (if necessary). This is especially
important in samples drawn after administration of hemoglobin-based
oxygen carriers (e.g. oxyglobin), which are colored compounds that
affect the results of many chemistry tests.
All of our chemistry tests that are components within panels can be
ordered individually, rather than as group tests. This is useful for
research samples. |

Group Tests |
|
| View the chemistry group test page for detailed
reports on certain tests and to obtain more information about the
individual components of each test, click on the test name below.
For those tests that do not have links, most of the information can
be gleaned from the other panels which include the same tests (mostly
small and large animal panels). |

Individual Tests |
|
| View the chemistry individual test page
for components of our panels can be ordered individually. There are
also some tests that are not included in the panel, which must be
ordered as individual tests. Click on certain tests to obtain more
information. Please refer to our Chemistry Module for additional information
about the tests, including disease associations. |
